Intel Wireless Charging Demo, Info and Updated Efficiency Prediction

Posted on 17 September 2012 by

I’ve already looked into wireless charging but at IDF2012 I got a chance to speak to the engineers about it and get a first-hand demo. Video below.

IDT are the company that is producing the first integrated TX/RX unit and you’re going to see it in solutions next year. Obviously it needs both Ultrabook and phone to have the same ‘standard’ and there won’t be many choices out there to start with. Intel phone + Intel laptop is going to limit you but there’s a chance we’ll see mice, headsets and other devices using this method. The Intel Smart Watch demo was cancelled at IDF but I ‘m guessing that was going to be a wireless charging demo – just look where your hand spends a lot of time when you’re using Win 8 touch!

In the video below I talk about efficiency and I note that Intel have updated their end-to-end efficiency prediction.

Wireless Charging efficiency Sept 2012


You’ll also see  the software which prevents wireless charging from occurring if the battery is below a set level.

I still don’t like the efficiency aspect of this but I have to agree it’s a very attractive method of charging a phone.

    I don’t see the efficiency as a big issue, because you are using a 40+WHr battery containing laptop to charge a 5WHr phone. That’s considering that you are on battery, not a worry if you are plugged in.

    Can anyone shed some light on this question:

    all this wireless streaming to loudspeakers or as in this case wireless charging .. does it encrease whatever there might be of electro-smog electro-magnetic fields which may effect human organisms in various way or is it just using the electro-magnetic waves which are already surrounding electronic device in this case ultrabook anyway ? maybe just as a radio or tv does when receiving the signals in the air?
